Dubbo-parent

For example, the parent project of dubbo is the dependencies dependency, properties and other configurations defined in the dubbo-parent,dubbo-parent project can be passed to the dubbo project, while the dubbo child project does not need important definition dependencies.

Note that if I put the dependencies in dubbo-parent on the outside

...

This form of dependency management, the dubbo project is not inherited by default, this is an optional dependency, you need to add your own dependencies that need to be inherited, do not need to take the version number, inherit the parent project by default.

Polymerization

Inheritance is done by defining the parent form, and aggregation is the module form.

Let's also look at the aggregation relationship through dubbox. Dubbox is the general project, and the following are all sub-modules. Note that the total project must be in the form of pom package in order to be an aggregation relationship.

Let's see how the module is defined.

Packaging, compiling and other operations on the dubbox will directly operate the sub-modules, without the need for us to package one by one on other projects.

At this point, the study of "the concept of Maven inheritance and aggregation" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
